On the aether-like Lorentz-breaking actions

M. Gomes, J. R. Nascimento, A. Yu. Petrov +1

We demonstrate the generation of the CPT-even, aether-like Lorentz-breaking actions for the scalar and electromagnetic fields via their appropriate Lorentz-breaking coupling to spi…

Free energy of Lorentz-violating QED at high temperature

M. Gomes, T. Mariz, J. R. Nascimento +3

In this paper we study the one- and two-loop contribution to the free energy in QED with the Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters…

On the effective potential in higher-derivative superfield theories

M. Gomes, J. R. Nascimento, A. Yu. Petrov +1

We study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential. In particular, we…

The Gödel solution in the modified gravity

C. Furtado, T. Mariz, J. R. Nascimento +2

We consider the modified gravity whose action represents itself as a sum of the usual Einstein-Hilbert action and the gravitational Chern-Simons term and show that the Gödel metric…

On the superfield effective potential in three dimensions

A. F. Ferrari, M. Gomes, A. C. Lehum +4

We develop the superfield approach to the effective potential in three dimensions and calculate the one-loop and two-loop kählerian effective potential in commutative and noncommut…
